# URL

A collection of utilities to manipulate URLs.

## Installation

Install the module

```bash
npm install @wordpress/url --save
```

_This package assumes that your code will run in an **ES2015+** environment. If you're using an environment that has limited or no support for such language features and APIs, you should include [the polyfill shipped in `@wordpress/babel-preset-default`](https://github.com/WordPress/gutenberg/tree/HEAD/packages/babel-preset-default#polyfill) in your code._

## Usage

<!-- START TOKEN(Autogenerated API docs) -->

### addQueryArgs

Appends arguments as querystring to the provided URL. If the URL already includes query arguments, the arguments are merged with (and take precedent over) the existing set.

_Usage_

```js
const newURL = addQueryArgs( 'https://google.com', { q: 'test' } ); // https://google.com/?q=test
```

_Parameters_

-   _url_ `[string]`: URL to which arguments should be appended. If omitted, only the resulting querystring is returned.
-   _args_ `[Object]`: Query arguments to apply to URL.

_Returns_

-   `string`: URL with arguments applied.

### buildQueryString

Generates URL-encoded query string using input query data.

It is intended to behave equivalent as PHP's `http_build_query`, configured with encoding type PHP_QUERY_RFC3986 (spaces as `%20`).

_Usage_

```js
const queryString = buildQueryString( {
	simple: 'is ok',
	arrays: [ 'are', 'fine', 'too' ],
	objects: {
		evenNested: {
			ok: 'yes',
		},
	},
} );
// "simple=is%20ok&arrays%5B0%5D=are&arrays%5B1%5D=fine&arrays%5B2%5D=too&objects%5BevenNested%5D%5Bok%5D=yes"
```

_Parameters_

-   _data_ `Record<string,*>`: Data to encode.

_Returns_

-   `string`: Query string.

### cleanForSlug

Performs some basic cleanup of a string for use as a post slug.

This replicates some of what `sanitize_title()` does in WordPress core, but is only designed to approximate what the slug will be.

Converts Latin-1 Supplement and Latin Extended-A letters to basic Latin letters. Removes combining diacritical marks. Converts whitespace, periods, and forward slashes to hyphens. Removes any remaining non-word characters except hyphens. Converts remaining string to lowercase. It does not account for octets, HTML entities, or other encoded characters.

_Parameters_

-   _string_ `string`: Title or slug to be processed.

_Returns_

-   `string`: Processed string.
